Attack function, support attacked part

[sinner]

Hi there, I'm working on an attack system, though, I'm wondering if anyone could give me some piece of advice on how should I process the data on attack function to keep track of whom support units have been killed in the battle.

If 80 % of all units die, every group (from the defending and the supporting villages) loses 80% of their troops, I think this is the way Tribalwars does it, and it's quite logical.

Yes it'q quite logic.. so I need to start counting dead units with the support units, till I reach that 80%..
